vector sum and magnitude

I need to create a function that will take two 3D geometric vectors as its arguments, sums them, and returns the resultant vector and its magnitude

[Geoff]

And your question is ..... ?

[Aakash Deep]

Your statement is contradicting. If the values are in 1 dimension then it is a vector, if the values are in 2 dimensions then it is a matrix and if the values are in 3 or more dimensions then it is a tensor. So, 3D vector does not make any sense.

Answer 1

[Geoff]

Maybe this will help:

function [vec, mag] = DoMyHomeworkForMe( v1, v2 )
  % Your calculation goes here
end

[Robert]

:) hahaha nice

[Robert]

how about a push in the right direction

[Geoff]

That WAS a push in the right direction. =P All you need to do is add your vectors together and find out how big the result is.

[Robert]

but how do i create a function that does so?

[Geoff]

Now we're going round in circles! Please see the code in my answer. The INPUTS are v1 and v2; the OUTPUTS are vec and mag. I think the names a self-explanatory here. You don't have to use the function name that I used.

[Robert]

function addtwo(x,y)

% addtwo(x,y)

% print the result = x + y

x+y

how do i allow x and y to be a vector?

[Geoff]

x = [1, 2, 3];

y = [2, 2, 2];

[Robert]

unbalanced or misused () or []

(thanks for helping me by the way)

[Geoff]

You're kidding... copy that exact code I wrote declaring two vectors (x and y) and paste it into MatLab.

[Robert]

i was copying it wrong! sorrrrryyy
